Rocketeer Unveils Lightweight Keiryo and 300HP Mk3 V6 MX-5 Conversion

British performance brand Rocketeer is entering an exciting new chapter in 2025, building on the success of 30 turnkey MX-5 conversions and over 150 self-build kits. With fresh funding from passionate automotive investors, the company is expanding its lineup with two new V6-powered Mazda MX-5 projects, set to launch later this year—one of which could become its most radical build yet.

Introducing the Rocketeer Keiryo: An Ultra-Lightweight V6 Sports Car

First up is the Rocketeer Keiryo, named after the Japanese word for “lightweight.” This new build is commissioned by a private client and promises to push the limits of what a Mazda MX-5 can be. The goal? A staggering 850kg curb weight and 375 horsepower, all while retaining the beloved Jaguar AJ30 3.0-liter V6 engine. With whispers of a 9,000 rpm redline, the Keiryo is shaping up to be a high-revving, analog driving machine aimed squarely at hardcore enthusiasts.

While the specifics of how Rocketeer plans to hit these ambitious targets remain under wraps, one thing is clear—the Keiryo won’t be a one-off. Enthusiasts who crave an ultra-light, V6-powered roadster can already register interest or place an order. Expect this car to appeal to those who want raw, mechanical thrills with a distinctly modern edge.

Rocketeer Expands Into NC MX-5 Territory With 300HP V6 Conversion

In addition to the Keiryo, Rocketeer is broadening its horizons by developing a V6 conversion for the Mk3 Mazda MX-5 (NC generation). Previously focused on the Mk1 (NA) and Mk2 (NB) models, this marks Rocketeer’s first foray into newer territory. The upcoming NC V6 conversion is expected to produce around 300 horsepower and is already in the final stages of development.

Thanks to the NC’s affordability and increasing availability, Rocketeer anticipates strong demand. With clean Mk1 MX-5s now commanding upwards of £10,000, many buyers are turning to the Mk3 as a more budget-friendly base. This new conversion package promises to transform the NC into a capable, soulful machine, blending modern reliability with old-school performance.

Investment Powers Growth and Global Expansion

Fueling this new wave of innovation is a recent investment by a group of automotive enthusiasts—people who own supercars, collect classics, and understand the enduring appeal of analog sports cars enhanced with modern engineering. This financial boost isn’t just helping bring the Keiryo and Mk3 V6 projects to life, but it’s also enabling Rocketeer to expand internationally, including the long-awaited ability to ship cars to the United States.

With build partners already established in Germany, the Netherlands, and Australia, the brand is poised to grow its global footprint significantly. The U.S. market, with its massive MX-5 fan base and tuner culture, is expected to be a game-changer for Rocketeer’s business.

Continued Focus on Custom V6 Conversions for All MX-5 Generations

Despite the expansion, Rocketeer remains committed to what made it famous: turning Mazda’s lightweight roadsters into bespoke, V6-powered performance machines. The company continues to offer its Turnkey MX-5 conversion, where only the Jaguar V6 engine is installed, as well as the RestoBuild option—a full restoration and performance overhaul completed in close collaboration with the customer. Every RestoBuild car also earns a spot in Rocketeer’s exclusive vehicle register.

Self-build kits will remain a core offering as well, catering to DIY enthusiasts looking for a more hands-on approach. But with two new builds incoming—the high-performance Keiryo and the next-gen NC conversion—demand is expected to soar. Patience may be required for new customers, but the wait promises to be well worth it.

Final Thoughts: A Bold New Era for Rocketeer

With a blend of cutting-edge engineering and classic driving philosophy, Rocketeer is redefining what it means to modify an MX-5. Whether it’s the featherweight Keiryo with supercar-rivaling power-to-weight, or the everyday practicality of a 300HP NC, the company is delivering something truly special for gearheads around the world. Backed by smart investment and growing international interest, Rocketeer’s future looks fast, fun, and fiercely analog.
